BLAINE B.PETERSEN n g I a /y6" ATTORNEYS United States Patent Ofiice 3,012,692Patented Dec. 12, 1961 3,012,692 DISPENSER PACKAGE COMPRISING A CON-TAINER AND FOLDED SHEETS STACKED THEREIN Blaine B. Petersen, 1034 E. 1stSt., Carnas, Wash. Filed Jan. 27, 1958, Ser. No. 711,463 4 Claims. (Cl.221-63) This invention relates to stacked and folded sheets of aflexible material and a container therefor in which the sheets are to becontained, thereby providing a novel and compact dispenser package.

More particularly the invention relates to a dispenser packagecomprising an outer container of a commercially available material, suchas bendable paperboard or the like, provided with a removable portionwhich, when removed, provides an access opening through which a consumermay grasp individual sheets of a stack of flexible folded sheets ofpaper or the like. The .sheets are positioned in the container forremoval individually therefrom in at least partially unfolded conditionready for use.

Dispenser packages of the type here involved are well suited fordispensing flexible paper sheets of substantially large size which areintended for industrial use, such as for wiping grease or oil from thehands of a mechanic or the like in a factory or garage, as well as fornumerous other uses in maintaining clean a work area in an industrialconcern. Dispenser packages of this invention also may be provided fordispensing sheets of various sizes intended for various uses, such asfor dispensing cleansing tissues of the well known type.

Regardless of the type of folded sheet to be dispensed and the sizethereof, a compact and sturdy dispensing package is produced which maybe readied for use merely by separating from the package container aremovable portion provided in at least one of the walls forming thecontainer. I

Summarizing this invention, it has as its objects, among others, theprovision of a blank of flexible material, such as paperboard, which isadapted to provide acontainer which forms part of a dispenser package;the provision of flexible folded paper sheets or tissues which are to bestacked within the container of the dispenser package free ofinterfolding with each other for easy removal therefrom individually;the provision of pull-tab means on each of the stacked sheets forfacilitating removal of individual sheets; the provision of spacer meansfor separating adjacent pull-tabs from each other to facilitate thegrasping of an individual pull-tab; and the provision of a removableportion intended to provide an access opening in at least one wall ofthe container through which individual sheets may be withdrawn in atleast partially unfolded condition ready for use and wherein suchremovable portion may be separated from the container in relativelysmall sections or segments.

The container within which the stacked sheets are received desirablycomprises a top and a bottom, opposite front and rear walls, and endclosure flaps hingedly connected to the opposite margins of each of thetop, bottom and front and rear walls of the container to form the endwalls thereof. Each of the flexible sheets comprises a body section withpull-tab means extending freely beyond the body section with suchpull-tab means being positioned adjacent the removable portion providingthe access opening in the container through which individual sheets maybe grasped by the consumer. The package thus provided is compact innature and is sufliciently sturdy to withstand the normally roughhandling which may be expected for a tissue or sheet dispenser packagein an industrial concern.

FIG. 8 is a plan view of the blank from which the container of FIG. 1 isset up;

FIG. 9 is a plan view of the blank from which the container of FIG. 6 isset up. 7

Referring first to FIG. 8, the inner surface of container blank 1 isillustrated which desirably is made from relatively sturdy but bendablepaperboard, but which may be made from any other suitable foldablematerial. Blank 1 is provided with a plurality of fold lines L whichextend longitudinally of the blank in substantially parallelrelationship. The fold lines L divide the blank respectively into abottom panel 2, a front wall panel 3, a top panel 4, a rear wall panel6, and a glue panel 7, all of which desirably are substantially equal inlength.

Extending transversely of longitudinal fold lines L and definingopposite margins of each of the panels 2, 3, 4 and 6 are fold lines T.Connected to opposite margins of bottom panel 2 along fold lines T areopposite end closure flaps 8. Similarly connected along fold lines T tofront wall panel 3 are additional end closure flaps 9 which desirablyare slightly longer than closure flaps 8. Additional pairs of endclosure flaps 11 and 12, which desirably are identical to the endclosure flaps 8 and 9 respectively, are secured to opposite margins oftop panel 4 and rear wall panel 6, respectively, along fold lines T.

Each of the end closure flaps is separated from the adjacent flap by acut C which provides a clearance space between adjacent flaps andfacilitates folding of the end closure flaps in a conventional manner toprovide the end walls of the container. As a result of cuts C, eachclosure flap is slightly narrower than its associated container panel.Appropriate inner surfaces of closure flaps 8 and 11 are coated with asuitable adhesive by means of which the container, when folded alonglines L and T in a conventional manner, may be maintained in the set upcondition shown in FIG. 1. The outer surface of glue panel 7 desirablyis coated with adhesive for engagement with the inner face of bottompanel 2 when the blank is set up. Prior to adhesively securing the endclosure flaps to provide the end walls of the container, a stack offolded sheets is positioned therein. Such stack may be inserted endwiseinto a partially set up blank or the blank may be folded and set uparound a stack of sheets which initially has been positioned thereon.

Front wall panel 3 and rear wall panel 6 desirably are of equal size buteach is slightly larger in transverse dimension or width than bottompanel 2 and top panel 4, thereby imparting a height to the containerwhen set up which is somewhat greater than its width. The exact size,however, of the respective panels may be varied as desired dependingupon the size, character and number of the folded sheets to be containedtherein.

Desirably, end closure flaps 9 and 12 are of the same size but each isslightly longer than end closure flaps 8 and 11. Because of the lengthof closure flaps 9 and 12, the edges thereof overlap when such flaps arefolded inwardly to form a container end wall. Flaps 8 and 11 arethereafter folded over flaps 9 and 12 and adhesively secured thereto tocomplete the end walls. The overlapping construction of flaps 9 and 12at each end of the container imparts added strength to the end wallsthereof thereby adapting the container for rugged handling withoutdamage.

Integrally connected to front wall panel 3 along spaced tear lines 14and 16 is a removable portion 13. Desirably the tear lines take the formof perforated lines which diverge from the line of juncture of bottompanel 2 and front wall panel 3. Lines 14 and 16 desirably extendsubstantially the entire distance between the bottom panel 2 and the toppanel 4. The size of the removable portion 13 is controlled by thespacing and amount of divergence of lines 14 and 16.

Another removable portion 17, which desirably is a continuation of theremovable portion 13, extends into the top panel 4 from the line ofjuncture of the front wall panel 3 and the top panel 4. Continuation 17is an integral part of top panel 4 and is removable therefrom along tearlines 18 and 19 which converge along a curved path from the line ofjuncture of front 'wall panel 3 and top panel 4 with the ends thereofterminating at cut 21 formed in top panel 4 at a location spaced fromsuch line of juncture. Cut 21 desirably is crescent shaped and providesa tab to facilitate removal of the removable portion 13 and continuation17 from the container.

The other ends of tear lines 18 and 19 communicate with the ends ofdiverging tear lines 14 and 16 in front wall panel 3 whereby lines 18and 19 are effective continuations of lines 14 and 16 respectively. Aout line 22 may be formed at the line of juncture of removable portion13 and removable portion continuation 17 to facilitate bending of theremovable portion along a line corresponding to fold line L when thecontainer blank is set up. However, the cuts at the ends of line 22desirably do not communicate with the cuts of lines 14, 16, 18 or 19thereby insuring that removable portion 13 will not accidentally besevered from continuation 17 when the latter is removed in the manner tobe described.

When a container is set up and a stack of sheets positioned therein toprovide a dispenser package, the removable portion may be removed toprovide an access opening 23 for the removal of the sheets by engaging afinger nail or the like under the tab formed by cut 21. Upon liftingupwardly on such tab, the continuation 17 of the removable portion 13may be separated from the container along diverging lines 18 and 19 totear the same from engagement with top 4. Upon continued pulling of thecontinuation 17 of the removable portion an access opening is providednot only in the top 4 of the container, but also in the front wall 3 ofthe container due to the connection of portions 13 and 17 along foldline 22. The access opening 23 which is formed upon removal of theremovable portion 13 and continuation 17 is illustrated in FIG. 3.

Because of the nature of an intended use of the package, for example, inindustrial plants, frequently it is desirable to remove part of theremovable portion 13 at one time, thereby maintaining part of theremovable portion connected with the container front wall and keepingthe tissue sheets in the package as clean as possible. Also, as aresult, the front wall of the container thereby is maintained intact toas great a degree as possible during use thereby imparting strength tothe container during its continued use.

The removable portion 13 in front wall 3 desirably is divided into aplurality of removable sections 24, 26 and 27 by spaced tear lines 28,29 and 31 which extend transversely between the diverging tear lines 14and 16. Tear line 31 desirably is coincident with fold line L connectingbottom panel 2 and frontwall panel 3. As a result of such constructionrelatively small individual sections of the removable portion 13 may beseparated from the front wall 3 as the supply of sheets remaining in thecontainer decreases. When the supply of sheets decreases to the level ofthe bottom of the access opening first provided when the package isopened, an additional section of the removable portion may be torn fromthe package thereby exposing additional sheets for use. To facilitatetearing out individual sections of the removable portion 13, crescentshape cuts 32 desirably are provided at the points of juncture of eachof the tear lines 28 and 29 with spaced tear lines 14 and 16.

By providing a removable portion 13 which progressively may be removedin relatively small section as described, the container package iscapable of retaining much of its initial strength during use and therebyis capable of withstanding the rough handling to which it is destinedwhen used in an industrial concern. Also, the folded sheets remaining inthe container are kept in a more clean condition in that the sheets nearthe bottom of the package are protected until ready to be used.

The shape of access opening 23 is determined by the direction in whichtear lines 14, 16, 18 and 19 extend. In the embodiment of FIGS. 1 to 3 arelatively large access opening is provided in that the pairs of foldlines 14 and 16 and 18 and 19 diverge toward fold line L lying betweentop 4 and front wall 3 of the container. The resulting relatively largeaccess opening provides sufiicient room for insertion of substantiallythe entire hand of the user into the container for grasping a section ofthe uppermost sheet in the package.

However, if desired, a substantially smaller access opening may beprovided in the container by modifying the spacing and direction inwhich the tear lines extend as illustrated in FIGS. 6 and 7. The blankshown in FIG. 9 from which the container of FIGS. 6 and 7 is formed isbasically similar to the blank of FIG. 8 and similar reference numeralsare used for similar parts, but all such reference numerals are primedto distinguish between the two containcr modifications illustrated.

The spaced out score lines 14 and 16' which provide the removableportion 13' are substantially parallel in the blank modification of FIG.9 thereby providing, when portion 13' is removed, a relatively narrowslot or access opening which extends in front wall 3' substantially theentire distance between bottom panel 2 and top panel 4.

The continuation 17' of the removable portion 13 is defined along oneedge by perforated tear lines 18' and 19'. Continuation 17' is connectedto removable portion 13' along an extension of fold line L between toppanel 4' and front wall panel 3. Tear lines 18' and 19' aresubstantially co-linear and communicate with opposite ends of a cut 21'which provides the tab which facilitates initial grasping and removal ofthe removable portion in the manner described previously.

Perforated tear lines 33 and 34 are provided in the line of juncturebetween front wall panel 3' and top panel 4' to define another edge ofthe continuation 17 Lines 33' and 34 are substantially parallelrespectively to lines 18 and 19' thereby imparting an elongatedconfiguration to continuation 17 of the removable portion and providingan elongated slot access opening in top 4' when continuation 17' isremoved.

The adjacent ends of parallel lines 18' and 33 are connected by a curvedperforated tear line 36'. A similar curved perforated line 37' connectsthe adjacent ends of parallel tear lines 19' and 34 respectively.

The removable portion 13 desirably is divided into a plurality ofsections 24', 26' and 27' by spaced transversely extending perforatedtear lines 28', 29 and 31 thereby adapting the removable portion 13 tobe severed from front wall panel 3' in small sections as describedpreviously.

Because of the relatively narrow configuration of the access openingprovided when the container modification of FIG. 6 is set up, the papersheets remaining in the container are maintained in a very cleancondition awaiting use by the consumer. However, because of the narrownature of the access opening in the front wall 3', only a portion of thehand, such as the forefinger and thumb, may be inserted into the slotfor grasping the uppermost sheet of the stack for removal from thepackage. In this connection, sheets grasped for removal are movedupwardly adjacent the slot opening in top 4' of the package and removedthrough such elongated slot in at least partially unfolded condition.

Various types of foldable sheets may be used with the container of thisinvention to provide a novel package. Two such sheets whichadvantageously may be used are illustrated in FIGS. 4 and 5. The sheetshown in FIG. 4, because of its characteristic fold, is generallyreferred to as a 2-fold sheet. Such a sheet includes a body section 38which comprises multiple folds of the sheet reversely folded 'accordianstyle one upon the other as illustrated. The multiple fold body section38 illustrated comprises four folds, but such a sheet may be providedwith as many folds as desired.

The outermost fold 39 of the body section 38, which will be theuppermost fold of the sheet when positioned in the container, hasintegrally connected thereto pull-tab means which extends freely beyondthe body section 38 and which is substantially co-pl-anar with theoutermost fold 39. Such pull tab means comprises pull-tab section 41which desirably extends substantially the full length of the elongatedpaper sheet thereby providing a substantial area to be grasped by theuser as well as providing means for engaging the container andmaintaining the sheet in proper position therein. Furthermore, becausethe pull tab 41 extends the length of the sheet, the possi bility of thepull tab being severed from the sheet upon rtlenciloval of the sheetfrom the package is substantially precu ed.

The multiple folds which comprise the body section 38 of the sheetdesirably are of equal size so that the pulltab section 41 extendsfreely beyond each fold of the body section. As shown in FIG. 2, thepull-tab sections 41 of a stack of sheets are positioned adjacent theinner face of the front wall of the container and desirably are incontact with such face throughout their lengths thereby insuring properpositioning of the stack of sheets in the container package.

Spacer means are provided in the dispenser package for separating thepull-tabs of adjacent sheets from each other so that individualpull-tabs may be grasped for removing individual sheets from thepackage. Such spacer means desirably are integral with the sheets andare provided by the multiple-fold body section 38 of each of the sheets.The spacing of one pull-tab from another may be varied by increasing ordecreasing the number of folds used in the multiple-fold body section 38or by using a paper material having increased or decreased thickness.

Z-fold sheets of the type described are shown positioned in thecontainer of FIG. 2 and are stacked one on top of the other. The sheetsin the stack desirably are not inter-folded in any manner, but eachsheet merely rests on the uppermost fold 39 of the body section 38 ofthe sheet lying directly therebeneath. When the pull-tab 41 of theuppermost sheet of the stack is grasped as shown in FIG. 2, and outwardmovement is imparted to the sheet through the access opening 23 as shownin FIG. 3, the Z- fold sheets described will, during their removal fromthe package, become completely and automatically unfolded and ready forimmediate use by the consumer. Such automatic unfolding is desirable inthat it is unnecessary for the user to manipulate the sheet in anattempt to unfold it, which frequently is most difficult when the usershands are covered with grease or the like. As shown in FIG. 3, when thetop sheet of the stack is removed from the package, it is pulledtherefrom at the section of access opening 23 which is the widest,thereby facilitating removal and complete unfolding.

A modification of the sheet to be used with a dispenser package of thisinvention is shown in FIG. 5. Such modification generally is referred toas a double-fold sheet in that the sheet first is folded over to producea double thickness sheet in which one edge thereof extends beyond theother edge to provide a pull-tab section. Subsequently such doublethickness sheet is again folded to bring the folded edge in line withsuch one edge thereby producing the,

double-fold body section shown in FIG. 5. The multiplefold body sectionof the sheet of FIG. 5 is designated 42, and in the illustratedembodiment comprises four folds of the sheet. However, more folds orless folds than illustrated could be used. The outermost fold of thesheet, which desirably is th uppermost fold when the sheet is in acontainer, is designated 43. Extending freely beyond the body section 42of the sheet as an integral extension of outermost fold 43 is pull-tabsection 44 which projects freely beyond the body section for readyaccess by the consumer.

Double-fold sheets of the type shown in FIG. 5 are adapted to be stackedone on the other without interfolding in the same manner as illustratedby the Z-fold sheets shown in FIG. 2. The pull-tab section 44 of eachsheet of the stack desirably engages the inner face of the front Wallthereby positioning the stack properly in the container and presentingthe respective pull-tabs of the stack for grasping through the accessopening of the container.

Because of the nature of the fold of the double-fold sheets described,upon pulling outwardly of such sheets from the container, the same arenot always completely unfolded as generally is the case when Z-foldsheets are used. Upon pulling outwardly on the pull-tab section 44 of adouble-fold sheet, the sheet is only partially unfolded; however,because the sheet is held only by the pull-tab section 44 which projectsbeyond the body section 42 thereof, the weight of the sheet itselfnormally is sufiicient to completely and automatically iuifold the sheetfor ready use upon removal from the container. To assist in theunfolding operation, however, a mere flick of the wrist of the user isall that is necessary to complete the unfolding operation if the weightof the sheet itself does not completely unfold the sheet upon removalfrom the package. As a result, regardless of the type of folded sheetused with the dispenser package, the ultimate consumer may use the sheetin its unfolded condition substantially immediately upon its removalfrom the package.

It should be understood that folded sheets of the type shown in FIGS. 4and 5, as Well as other similar sheets, may be used with either of thecontainer modifications shown in FIG.1 or FIG. 6. 7

While the dispenser packages described herein are particularly welladapted for dispensing relatively large sheets of single or double plywiping paper of the like, other types of folded sheets or tissues alsomay be used, and materials other than paper similarly could be used.

The materials described herein are intended as being merelyillustrative.

One specific example of a dispenser package of the type shown in FIGS.1-3 will be described. Bottom and top panels 2 and 4 of the packagecontainer are approximately 4- /8 inches wide by 15 inches long. Frontwall panel 3- and rear wall panel 6 are approximately 4% inches high 15inches long. End closure flaps 9 and 12 connected to front wall panel 3and rear wall panel 6 respectively are approximately 4% inches wide and2% inches long. End closure flaps 8 and 11 connected to bottom panel 2and top panel 4 are approximately 4% inches wide by 2% inches long. Whenthe container is set up, closure flaps 9 and 12 at each end of thecontainer overlap approximately 1% inches.

The folded sheets adapted to be dispensed from the package are onlyslightly less than 15 inches in length, thereby adapting the sheets tobe snugly received within the set up character. When unfolded the sheetsare in the shape of a square measuring approximately 15 inches on aside. The multiple-fold body section of each sheet is approximately 3%inches wide with the pull-tab section extending beyond the outermostfold of the body section approximately /2 inch. The removable portion 13of the container increases from a width of approximately 1 /2 inches atthe container bottom to about inches at the container top and is dividedinto three sections each approximately 1%; inches in height. Theforegoing description is illustrative of only one embodiment of adispenser package of this invention and folded sheets and containers ofother sizes obviously may be employed.

One form of paper sheet which has been found desirable for use asindustrial wiping tissue of the types herein described is a two-plysheet which may be embossed to impart an attractive pattern to the sheetand to impart sturdiness and strength thereto thereby adapting the sheetfor rugged use. Other types of sheets also may be employed, however, andthe type of sheet selected will depend upon the use intended for thesheet.
